Fig. 2 is a central, side sectional view showing two cars attached by means of my improved device.

Fig. 3 is an end elevational view,'of a car equippedV with my improved coupler.

Fig.,4 is a similar view. y

In the accompanying drawing, we have illustrated cars such as ordinarily used for mining purposes, having flanged wheels l0, rotatably attached to the truck 11, which supports a body 12, having sides 13 and ends 14, one of the ends being hinged to the sides, as designated by the numeral 15, by supporting members 16. The hereinbefore mentioned construction being in general, common to cars of this vnature and type, lit

Y y will be understood that we do not confine our invention to this particular type of mining car, but to mining cars of all classes and description. i v

As here embodied our improved coupler comprises two members 17 and 18. The member 17 has a lower portion 17 conveniently located aperture 19 to accommodate the U shaped supporting bar 20, which is attached to the car by a pin 22, it being understood lthat the member 17 is swingably attached to the supporting bar 2O,l and has an` elongated aperture 23 extended therefrom, by the extension 23 and a suitable support 24 for the counter-weight 25, which is slidably attached thereto by means of a screw 26, or any similar suitable means.

, The member 18 has an aperture located at or near one of its extremities to accommodate the pin 27, as a. means of attaching the said member 18 to the car, and is also provided with an extended portion 28, and an upright hook shaped piece 29, either integral taclied Qtoathe memlier asA at 32 (and, islso 6o ltl tthe semi-,circular,portion31.11.,.

vThe functioningeoroperation of our improved coupler for mining cars is as follows, themember 18 is so positioned that its extended portion 28 will strike the lower portion 17 of the member 17, when the two cars equippedV with my improved devicev are backed or otherwise forced toward onev another, whichwill cause the said member 17 to swing on the support 24, the elongated aperture 23 will thereby be swung outwardly and will strike the spring 30, forwardof the hook shaped piece 29, and will force the spring 30 downward momentarily, which on the support 24, preferably as designated a by the number 37, so as to assure the action as described above, it beingy obvious that the said counter-weight 25 is sopositioned as to normally holdl the member 17 in an upright y position. a Y

lVhile we have above described thepre- A ferred form, construction and arrangement of the several elements employed, it will be understood that the device is, nevertheless, susceptible of considerable modification therein, and we therefore reserve the privilege of resorting to all such changes as may be fairly embodied within the spirit and scope of the invention as claimed.

` Having thus described our invention, what we claim as new and desire to protect lby Letters Patent of the United States is as follows: y Y Y 1. A'coupler for mining cars comprising @sbt.Welfareriferledable@ f another, and a resilient'member positionedto.

receive one of said members and force it into locked engagement with the other member, which will cause the first mentioned member to engage with the second mentioned member.

3. A coupler7 self operating, for mining cars comprising two'members, so positioned that the extended portion of one member will strike the lower portion of the other member, when the said cars are forced toward one another, which Will causeY the first mentioned member to swing on a support, an elongated aperture located therein will be swung out- Wardly and will permitan extension to en- 'gage with the second mentioned member.

4. A kcoupler for` mine cars, comprising a loop memberswingably attached to one of said cars, a. hook member secured ,to the adjacent end of another car, means extending from said last mentioned car in position to register With one end of said loop member and adapted to strike and swing the latter towards said hook member, a spring secured at one end and formed at the other to conform with the curvature of said loop member for receiving and moving the latter into`Y locked engagement with said hook member. In testimony Whereor We have affixed our signatures.
